I leveled all the classes to 80 and DH feels the best. It only has 4 major cool downs, 2 for offense 2 for defense. 1 CD for mobility, 2 short rotation CDs and 6 normal rotation buttons. With some other utility skills.
Easy to learn and easy to play. If you want new players Havoc is the design to aim for, for all specs.
FYI I just copied murlok blitz spec so I’m sure there are some specs with more bloat.
